SNMP Problem
Hi, basically I'm just looking at the O'Reilly book 'Essential SNMP' and am following one of the examples. The code in the example is:

Code:
#!/usr/bin/perl
use SNMP::Util;
my $MIB1 = $ARGV[0];
my $HOST = $ARGV[1];
($MIB1) && ($HOST) || die "Usage: $0 MIB_OID HOSTNAME";
my $value = &snmpget("$HOST","$MIB1");
if ($value) { print "Results :$MIB1: :$value:\n"; }
else { warn "No response from host :$HOST:\n"; }

And the errors I'm getting are:

Code:
"my" variable $value masks earlier declaration in same statement at /usr/perl5/5.8.4/lib/SNMP/Util.pm line 804.
"my" variable @oid_names masks earlier declaration in same statement at /usr/perl5/5.8.4/lib/SNMP/Util.pm line 1636.
Undefined subroutine &main::snmpget called at ./snmpTest line 8.

Any ideas?

NAME

       SNMP::Info::Layer2::Airespace - SNMP Interface to Cisco (Airespace) Wireless Controllers

AUTHOR

       Eric Miller

SYNOPSIS

	   #Let SNMP::Info determine the correct subclass for you.

	   my $airespace = new SNMP::Info(
				 AutoSpecify => 1,
				 Debug	     => 1,
				 DestHost    => 'myswitch',
				 Community   => 'public',
				 Version     => 2
			       )

	   or die "Can't connect to DestHost.
";

	   my $class = $airespace->class();
	   print " Using device sub class : $class
";

DESCRIPTION

       Provides abstraction to the configuration information obtainable from Cisco (Airespace) Wireless Controllers through SNMP.

       For speed or debugging purposes you can call the subclass directly, but not after determining a more specific class using the method above.

       my $airespace = new SNMP::Info::Layer2::Airespace(...);
